danita, I have a TENS machine which I've been using when I get niggles but stupidly have forgotten about now that there's lots of pain! Will pull that out of my hospital bag and give it a go tonight.

HotI it does seem to be sciatic pain as when I walk I get pain shooting into my hip and down as far as my knee! Might get DF to rub my bum and thigh while I attempt to curl up Have been bouncing on my gym ball and getting on my hands and knees but might try spending more time doing that. Will check out the local pool and see how easy it will be to get out.

Mother Goose, thanks for the suggestion but ice just makes the pain worse. You'd think it would help, but for me personally I just find that it makes my muscles tense up too much which causes my back to spasm.

Thanks for the suggestions guys, it's much appreciated
